Standard Bandpass Filters

Andover's optical bandpass filters represent our comprehensive solution for precise spectral isolation across ultraviolet, visible, and near-infrared wavelengths. Specifically engineered to transmit well-defined energy bands, these filters feature wavelength ranges optimized for laser, mercury, biomedical, and analytical applications.
Each filter is precision-manufactured and mounted in protective black anodized rings to ensure durability and performance stability. Our extensive selection of standard sizes (12.5mm, 25mm and 50mm diameter) ships with calibrated spectral data and permanent part number identification.
Custom configurations are readily available to meet specialized requirements. With our efficient manufacturing processes and substantial inventory, we deliver most standard filters within two business days, with expedited one-day shipping available for urgent needs.
